تحليل فترات الجفاف و الرطوبة في محطة شحات

Abstract EN

Drought is the result of the interaction of a group of climatic elements, but the element of rain alone can be relied upon as an indicator of it،The purpose of this study is to analyze the periods of drought at the Shahat station over the period of time (1945-2007), to describe the characteristics of these periods and to pay attention to their time and quantity changes, The method of statistical analysis of the data was based on the Thornthith equation, which is one of the most widely used equations in drought analysis.

The Khosla equation was used to determine the water deficit.

The Evanon equation was used to extract the evaporation amount as well as the formula of FAO to calculate the equation of evaporation potential.

This study, based on the data of the Shahat station, which is part of the Green Mountain climate, shows a scarcity of severe droughts, both in terms of the amount of rainfall and the length of periods of drought and decrease, which is of utmost importance to the region in terms of the importance of agriculture and the optimal utilization of these natural resources.

The study also showed that there are no normal cycles of the rain system so that their quantities can be predicted.

However, it is clear from the statistical analysis that there is a minimum annual rainfall range of not less than 300 mm per year.

This study recommends the reoperation of the Shahat Climate Station and careful recording of climatic data, especially as the data of the Shahat station represent a historical record of climate throughout the region of the Green Mountain Region
